Magnetic dimensionality and the crystal structure of two copper(ii) coordination polymers containing Cu and Cu building units.

The electrostatic self-assembly reaction of the [Cu(HL)] cation, where HL = 2-(2-aminoethylamino) ethanol, and the N or [Fe(CN)] anion leads to the formation of two coordination polymers with the general formula of [Cu(μ-N)(μ-N)(μ-N)(μ-N)(HL)] (1) and {[Cu(HL)][Fe(CN)]·HO} (2), respectively. The resulting compounds have been structurally characterized by a single-crystal X-ray diffraction technique. Compound 1 possesses a rare 3D structure.
